Application filed April 1a, 1908. min No. 427,875.

To all whom it may concern:

Be it known that I, Gus'rar DALr'iN, engi neer, subject of Sweden, residing at Stockholm, Sweden, have invented new and useful Improvements in Filling Masses for Receivers for Storing Explosive Gases, of which the following is a specification.

- It has been previously proposed for the purpose of storing explosive gases, such as acetylene gas, to employ blocks or bricks of porous material, such as asbestos, pulp and the like, which have been introduced isng blocks or bricks however necessitate a comparatively large opening in the receiver, for their introduction, and said openin must be closed by a cover, which in turn is difficult to get sufiiciently tight and moveover augments the weight of the receiver. For this reason it has been held more convenient to employ rolled receivers of the kind commonly used for storing liquid carbonic acid and to employ the filling substance in a pasty condition, so that it can be introduced in the receiver through a small opening, closed by a screw plug. The substance hitherto employed for this purpose has constituted substantially a ceramic material, such as cement, lime, clay or the like mixed with charcoal and silicious earth. Or it has been composed of charcoal and silicious earth mixed with some absorbent, such as -zinc oxid and zinc chlorid. Said substance has shown the inconvenience of bursting, when the same after having been filled in the receiver, is dried, so that the filling in fact has not constituted a whole brick, which is desirable for storing the acetylene gas.

The resent invention has for its object to avoid the disadvantages of prior compositions for the purpose specified and to produce a pasty mass which can be introduced through a. small opening in the gas receptacle and which will be thoroughly satisfactory in use.

My invention consists broadly in incorporating fibers of elastic or plastic material, such as asbestos or the like, 1n pasty ceramic material in such proportions that the resultmg mass will be of a tough fibrous consistency.

The following ingredients mixed in the proportions specified yield a composition which is well adapted to serve the purposes of the invention:

Clay 20 grams Silicious earth 10 Charcoal 10 Zinc oxid 5 chlorid 5 -Asbestos fiber 5 Satisfactory results may be obtained by the use of pasty ceramic material and asbestos fiber alone, or with charcoal added thereto, but the best results are obtained by the use of the ingredients specified.

In using the material,-it is introduced in the usual manner through a hole in the receiver and is thereafter heated to thoroughly dry and harden the mass.

Having described my invention, I claim:

1. A filling mass for receivers for storing explosive gases, comprising pasty ceramic lnalterial mixed with fibers of elastic materia 2. A filling mass for receivers for storing explosive ases, comprising pasty ceramic material, 0 arcoal and fibers of elastic material.

3. A. filling mass for receivers for storin explosive gases, comprising pasty ceramic material, charcoal, silicious earth and fibers of elastic material.

4. A filling mass for receivers for storing explosive ases, comprising pasty ceramic material, ciarcoal, silicious earth, zinc oxid, zinc chlorid, and asbestos fiber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GUSTAF DALEN.
